what does << do? mysql

[Silver-0-surfer]

Hi

I need to edit a mysql query thats currently like this (writing from php)

insert into table (row) values ('$var1' << 32 | '$var2');

but I just have no idea what << is or even what its called so I can read about it (google doesn't really bring anything up, sort of ignores it).

any brief explanations or even what its called would be great.

Thanks
